Due to the Soviet conquest of eastern Germany, Schichau moved to Bremerhaven in March 1945, and its successors continued in business until 2009.

It started with the production of hydraulic presses and diggers; in 1860, it began to produce locomotives for the Prussian Eastern Railway.

[1] The engine of S 1, which was built by Schichau in 1884 as one of Germany's first torpedo boats, is shown on display in the Deutsches Museum in Munich today.

[2] When Ziese died in 1917, the management of the company passed to the husband of his only daughter, Hildegard, the Swede Carl Carlson.

During World War II, Schichau built 94 U-boats for the Kriegsmarine (German Navy) at its Danzig shipyard.

The prisoners received inadequate rations: half a litre of thin soup and 250 grams of bread per day.

Bodies were burned in a crematorium but also buried in mass graves at the cemetery in Saspe (now the Zaspa district of Gdańsk).

[3] Up to the end of the war in 1945, the Schichau-Werke had supplied about 4,300 locomotives of several classes to customers that included the Deutsche Reichsbahn and GEDOB formed from disbanded Polish State Railways.

In March 1945, as Soviet forces approached, Hermann Noë, the chief executive, and some employees fled Danzig with uncompleted ships to Bremerhaven.

After the Western Allies lifted the ban on shipbuilding in West Germany in 1951, Schichau reopened its shipyard in Bremerhaven.
